Convert HTML Pages to ASPX Pages

I need to have approximately 150 HTML pages converted into ASPX (ASP.NET) pages. I am managing a new website, for which the content was retrieved using HTTrack Website Copier. Therefore each page is currently a static HTML page. I have created an ASP.NET Master Page for the site, and now I need all of the HTML pages converted into ASP.NET Content Pages. The content itself is simple, and the structure of the pages is very straight-forward (content always appears within a div tag having id="content"). Attached are 3 sample files: 1. [login to view URL] shows an example of what the existing HTML pages look like. 2. [login to view URL] shows an example of what the ASP.NET Content Page should look like. 3. [login to view URL] shows the new ASP.NET Master Page file that every Content Page must reference.
